Title: An improved tungsten arc lamp
IPC: H01J61/98
Filed: 1926-06-19
Abstract: 263,405. General Electric Co., Ltd., (Assignees of Patent-Treuhand-Ges. f³r Elektrische Gluhlampen). Feb. 3, 1926, [Convention date.]. Arc lamps.- In a direct-current lamp two or more tungsten anodes 12, 13, connected in parallel through separate resistances, co-operate with a single cathode 9, which may contain theoria. The fiat anodes 12, 13 may be separated by a narrow gap 16 inclined to their common plane, so that they form an unbroken luminous source. Their light-emitting surfaces 12<1>, 13<1> remote from the cathode 9 may be roughened or ribbed. Either the cathode or the anodes may be moved for striking the arc; as shown, the hemispherical cathode is carried by a bi-metallic strip 17, and may, when cold, make contact with one or both anodes. Several anodes may be arranged in a circle around the cathode. In order to allow of large currents, say 8 or 9 amperes per anode, the bulb contains nitrogen mixed with 2-10 per cent of a gas of low anode fall, say argon or mercury. The pressure of the nitrogen may be 860-70 mm. A separate switch 18. 19 may be provided in series with each anode. The electrodes are connected to pins 5<1> 6<1>, 7<1> on a cap 2.

Patent GB-401390-A (GB)
Title: Improvements in electro-magnetically-operable electric switches
IPC: H01H50/88
Filed: 1932-06-02
Abstract: 401,390. Electromagnetic interrupters. RAMSDEN, L. A., 80, St. Ives Road, Platt Lane, Rusholme, Manchester. June 2, 1932, No. 15584. [Class 38 (v).] An electromagnetic interrupter has a spring- operated contact member arranged to energise alternately two operating electromagnets or solenoids, to operate a contact lever or switch arm the speed of movement of the contact lever or switch arm being controlled by an escapement mechanism, adjustable fixed contacts being provided to vary the duration of travel of the contact lever. As shown in Fig. 1 the solenoids B, B are energised alternately by the movements of a spring-operated contact-member a<3> which oscillates between relatively fixed contacts a<4>, a<4>. The movement of the contact member is effected through a reciprocating core b having a pin b<1> engaging a slot d in a pivoted arm D which bears a pin d<1> engaging a slot a in a lever A pivoted at a<1>. The outer end of the lever A is connected by a dead-centre spring a<2> to a pin and lever A<1> also pivoted at a<1> and carrying at its free end the movable contact a<3>. The lever A<1> is connected by a link c and gearing c<1> ... c<7> to an escapement c<8>. On energisation of an electromagnet B the core b is attracted and the consequent swinging over of lever D brings the spring a<2> across the dead-centre position. The contact a<3> is moved slowly across towards the other fixed contact under the control of the escapement, its engagement therewith serving to complete the circuit of the other electromagnet B and thus to initiate a succeeding operating cycle. The oscillation of the lever D may be utilised to operate controlled circuits by means of pins d<4> (Fig. 7), which engage and step round a star wheel D<1> driving around cams F, F<1> (Fig. 8), these cams being arranged to operate rollers g carried by pivoted cams g<1> to which are attached spring contact blades G co-operating with fixed contacts 6. A spring detent e engaging the pin d<2> holds the lever D in its displaced positions. The fixed contacts a<4> are carried on an insulated plate A<3> adapted to be adjusted by a screw a<5> to vary the frequency of operation of the interrupter by increasing or decreasing the distance of travel of the movable contact a<3> under the control of the escapement retarding device.

Title: Improvements in a process for the preparation of crustless cheese
Inventor: DUBBERS HANS
IPC: A23C19/082
Filed: 1937-06-04
Abstract: A melting salt for use in making crustless cheese consists of a fused mixture of alkali metal orthophosphates with calcium salts or calcium oxide, the fused mixture being free from water of constitution.  In an example, sodium dihydrogen-orthophosphate and sodium monohydrogen-orthophosphate are heated with calcium oxide or a calcium salt, e.g. calcium carbonate, to the point of quiescent fusion at about 700-900 DEG  C.  The potassium may replace the sodium phosphates.  All water of constitution escapes during the heating and the complex calcium-alkali metal phosphates formed are finely ground. The salts may be adjusted to a desired pH range determined in aqueous solution by varying the composition of the melt, e.g. made more alkaline by adding more sodium monohydrogen-orthophosphate or soda.ALSO:Crustless cheese is prepared by fusing hard or soft cheese with a melting salt consisting of a fused mixture of alkali metal ortho-phosphates with calcium salts or calcium oxide, the fused mixture being free from water of constitution.  Known melting salts, e.g. alkali metal ortho- or pyrophosphates or salts of edible organic acids may be added to this melting salt.  In an example, the melting salt is prepared by heating sodium dihydrogen orthophosphate and calcium oxide or a calcium salt, e.g. calcium carbonate, up to the point of quiescent fusion at about 700-900 DEG  C.  The potassium may replace the sodium phosphates.  All water of constitution escapes during the heating and the complex calcium-alkali metal phosphates formed are finely ground for use with the cheese.  The salts may be adjusted to a desired pH range, determined in aqueous solution, by varying their composition, e.g. made more alkaline by adding in the melt more sodium monohydrogen orthophosphate or soda, or by mixing the melting salt with other phosphates, e.g. tetrasodium pyrophosphate.  A higher melting temperature, 80-90 DEG  C., may be employed for the cheese even with fat-rich varieties such as Emmenthal, Gorgonzola or Cheddar. Specification 378,918 is referred to.

Abstract: 1,117,716. Knitting machines. STOP-MOTION DEVICES CORP. 5 April, 1967, No. 15698/67. Heading D1C. A device for detecting faulty needles or an accumulation of yarn or fluff on a needle and to thereby initiate stoppage of the machine, comprises a pointer 16 extending from a plunger 18 slidable in a casing 12 and projected against the action of a spring 14 to present the pointer adjacent the needles. The pointer is retained projected by a boss 36 on the pointer engaging behind a projection 28 extending into a slot on the end of the casing the arrangement being that if the pointer is deflected in either one direction sideways or the other the boss 36 disengages the projection 28 and is immediately withdrawn by the spring 14. To facilitate the sideways deflection of the pointer its shank is reduced as at 34. When the pointer is withdrawn the plunger engages the end sleeve terminal 38 in an end cap 22 and completes an electrical circuit which causes the machine stop motion to operate.

Title: An improved hydro-electric motor
IPC: B60T13/68
Filed: 1927-06-15
Abstract: 272,928. Compagnie Internationale des Freins Automatiques Soc. Anon. June 17, 1926, [Convention date]. Fluid-pressure. - Apparatus for operating brakes, doors, railway points, &c, comprises a main reservoir 8 containing a supply of liquid under pressure, an auxiliary reservoir 3 for accumulating exhaust liquid, and a pump for returning the exhaust liquid to the main reservoir, the brakes &c. being operated by pistons 25 and/or the pump piston 5. The liquid from the reservoir 3 passes through a valve 15 and forces back the pump piston 5, until the latter actuates a switch 9 to close the circuit of an electromagnet 36 supplied by a battery 12. A switch 37 is thereby closed, and the solenoid 6 returns the piston to force liquid through a valve 14 into the reservoir 8. When it is desired to use the pump piston as an additional or the only means for operating mechanism, a slot on its rod engages a pin on an operating lever 20, so that during operation as a pump the lever 20 is not moved. In order to enable the piston to move farther so as to operate the lever, a switch 13 is placed in the position S. A valve 11 is thus opened by a solenoid. and the circuit containing the electromagnet 36 is interrupted. When the switch is in the position D, it opens the circuit of the solenoid for the valve 11, and closes those of the electromagnet 36 and of a solenoid 15<1>. Should the circuit in the line L, which normally energizes a more powerful opposing solenoid 15<11> fail, the solenoid 15<1> acts to open the valve 15. The Specification as open to inspection under Sect. 91 (3) (a) states also that the auxiliary reservoir may be formed by the pump cylinder. This subject-matter does not appear in the Specification as accepted.
